强群是蜜蜂安全越冬的基础

本文根据蜜蜂越冬的生活特点,选出五群不同群势的意大利蜜蜂,在相同条件下进行越冬蜂死亡率和消耗饲料的测定。通过计算得出越冬期蜜蜂死亡率与群势成强负相关;越冬期每公斤蜜蜂消耗饲料与群势成完全负相关。说明了强群抗御低温的能力强,消耗能量和饲料少,寿命长,越冬死亡率低;弱群抗御低温能力弱,消耗能量和饲料多,寿命短,越冬死亡率高。因此,强群是蜜蜂安全越冬的基础。

The Strong Group Being Basis of Safe Living Through the Winter of Bees

In the paper, the rate of death and coasuming of feeds of Italianbees from fiue groups which are a vared group potentil Cere determined in the same conditins, in terms of the characteristics of their Iiving through the winter.we knew that there is a strong negative correlation between the rate of death living through the winter and the group pootontial and an entire negative correlation between the consumed feed of bees per kg.and the group pxotential by the count.The results have showed that the strong groups are stronger ability preventing from low temperature, Iess cnergy and feed consumed, Ionger Iife and lower rate of death than the weak group.
